According to the British "Financial Times" website reported on November
9, under the support of millions of British pounds provided by the
British Ministry of Defense, British scientists made The world's first
quantum "compass" - an anti-jamming navigation device that does not rely
on global positioning satellites (GPS).
The report says that
the device can determine the exact location of anything on the planet
without being disturbed because it does not rely on external satellites.
The report said that Joseph Cotter, a researcher at the
Imperial Institute of Cold Matter at the Imperial Institute of
Technology, said: "It is completely immune to outside influences. If you
want to be a large vessel or autopilot for a long time." Car
navigation, its use is particularly large, no need to send or receive
any other signals."
The report said that the Ministry of Defense
has been investing in the construction of an independent navigation
device. It believes that such a device can be used for special purposes
on its nuclear submarines, which require secret navigation and
isolation from the outside world.
UK team has demonstrated a transportable, standalone quantum accelerometer at the National Quantum Technologies Showcase.
The quantum accelerometer has precision and accuracy possible by
measuring properties of supercool atoms. At extremely low temperatures,
the atoms behave in a ‘quantum’ way, acting like both matter and waves.
The report believes that
although GPS is the de facto global navigation system, its dependence on
space satellites means that it may be blocked, intercepted or
obstructed.
The report said that, in particular, it is extremely
vulnerable to vandalism or attack. "The satellite may sometimes lose
its signal due to space environment or high-rise buildings, or it may be
maliciously shot down or deceived, so you will think that you are in a
certain place, but it is not." he said. "On the earth, GPS signals
can't be received anywhere."
The report says that this new system
called quantum accelerometer works by measuring the speed of objects
over time. The change that has taken place. Although accurate
accelerometers exist in devices such as cell phones and laptops, they
must be recalibrated frequently. If used for navigation, they can only
work for up to several hours at a time.
This quantum device
measures the very low temperature - near absolute zero - the movement of
ultra-cold atoms; in this ultra-cold state, it is manipulated and
controlled with a custom-made powerful laser. they. The laser was
developed by Glasgow-based MSquared for nearly three years.
The
report quoted Grammar Malcolm, founder and CEO of MSquared, as saying:
"Now the pirates are very sophisticated and will interfere with the ship
by disturbing the GPS, enticing the ship to hit the rocks or boarding
the ship to gain control. In the area of defense and security, this
may be a bigger problem because the resilience and security of cities
and countries will be affected. This new device is an absolute reference
to the atomic level.”
The report said that the development of
the navigation device was funded by the Defense Department's research
department, the Defense Technology Laboratory, the UK Engineering and
Physics Research Council, and the UK Innovation Agency.
Introduction,
in 2013, quantum research was identified as a priority area by the
British government, with a focus on military technology. Since then,
through the British National Quantum Technology Program, the UK
government has invested 270 million pounds (about 350 million US
dollars) in projects in this field within five years.
